High-voltage transformer parasitic resonant PWM DC-DC high-power converters and their performance evaluations

The main purpose of this study is to describe some particular characteristic features and inherent benefits of series, parallel and series-parallel resonant tank inverter-fed DC-DC converters for medical-use X-ray high-voltage generators from a practical viewpoint. The method to treat the parasitic resonant circuit parameters of the high-voltage high-frequency transformer used in three typical resonant tank topologies is discussed on the basis of some simulation results, and the simulation results are also verified by experiments.
